Yeah, I am looking for useful light and I don't care too much for the lights that hang on the side of an AG pool. The GlowBuoy looks like it would fit the bill, but seems kind of expensive for what it is. Also, I'm not sure how often we would really use it since I would also have to figure out some way to control the mosquitoes before we do any night swimming. However, GlowBuoy looks like it could pull double-duty as a camp light or when the power goes out.
